This massive wall of dust is a terrifying sight to behold.
When it comes to the weather, there are few sights as intimidating as a haboob dust storm. Remember that scene in "Mad Max Fury Road" where the chase drives straight into a massive sand/thunderstorm? That was a haboob. The name comes from an Arabic word for sandstorms in parts of the Middle East.
Storms like that are not just Hollywood special effects either. They are very real weather phenomenon that are hazardous to motorists because of the high winds and lightning they can bring to an area.
According to the National Oceanic and Atmospheric Administration (NOAA), haboobs are most common in dry, arid and semiarid regions where large thunderstorms can blow through quickly and cause tons of damage. These windstorms usually form as a storm is dying and releasing heavy rains. For one of these storms to form, the strong winds must push down, often in a microburst or downburst. When the winds hit the ground, they pick up loose dust particles forming the giant clouds of sand you saw here. While this type of storm is often associated with places like Sudan, Iraq, Kuwait, or parts of Africa, and Australia, these storms can happen almost anywhere, especially in places with a monsoon season. Wind speeds can reach 60-70 miles an hour in the right circumstances, making them dangerous storms. Not only can they bury a place in a lot of sand quickly, they can also knock down power lines and cause traffic accidents with drivers who cannot see.
One massive Arizona dust storm went wildly viral in 2018 after striking heavily populated Phoenix. Other dust storms like this have been recorded by meteorologists in Texas, Colorado, New Mexico, California, Washington, and even as far North as Idaho. Note that most of these are in the Southwest. NOAA says Southern Arizona may be hit with up to three of these every year.
While the National Weather Service can put out dust storm warnings sometimes, these storms often hit quickly and with little warning. NWS recommends pulling off the road and turning your lights off if you get caught in one in your vehicle. Turning the lights off helps to keep other drivers from being confused and crashing into you while trying to follow. The good news is that most of these storms last less than 30 minutes, so you should be able to wait them out. Chalk it up as yet another one of nature's more fantastic sights!
